Force alchemy[1] , better known as Sith alchemy, was a science that referred to a number of areas under the Sith. It encompassed any power or technique which used the Dark side of the Force to permanently alter an item or living being.

Sith alchemy was primarily used to enhance the strength of weapons and armor (such as the famous Sith swords), or to genetically engineer and enhance alien species, making them more dangerous and easier to control by the Sith Lords. More sinisterly, Sith alchemy was capable of waking the dead in servitude to the Sith. Korriban zombies, and possibly Sith undead, were creations of this branch of the art.[3]

One of the many applications of Sith Alchemy was the art of creating nefarious toxins, such as Sith poison.

While he was on Yavin 4, the Sith Lord Exar Kun used alchemy to create terrifying creatures twisted by the dark side's influence. Around this time, the Sorcerer of TundKarnak Tetsu practiced Sith alchemy.[6]

The Prophet of the Dark SideCronal was referred to as Sidious' "monster-maker", and was responsible for the creation of such sithspawn as Gorc and Pic through the dark art of Sith Alchemy.[9] Cronal also created a specialized helmet that, when used, would amplify his dark side powers to an astounding degree, as well as allowing him to draw on the force abilities of other force-sensitives called the Pawns.
